Iggy Azalea

The Australian hip-hop star is a much buzzed-about 22-year-old rapper who is poised to set 2012 on fire with the upcoming reissue of her breakthrough mixtape, Ignorant Art, a forthcoming debut album entitled The New Classic—produced by T.I.—as well as a Levis ad campaign. Azalea has earned her buzz, though. She’s a fierce rapper with killer beats who does not shy away from beefs (most notably with fellow up-and-comer Azealia Banks) and from controversy (her song “D.R.U.G.S.” has raised more than a few eyebrows.)
